As well as the (now) standard set of graphs related to increasing greenhouse gas concentrations , rising temperatures , reducing glacier mass, etc., since the 1850-1900 baseline is very clearly associated with the increases in greenhouse gases, slightly (and decreasingly) modulated by the changes in atmospheric pollution.

Step 1: There is a natural greenhouse effect. This means that there is an upward surface flux of IR around (~398 W/m 2 ), while the outward flux at the top of the atmosphere (TOA) is roughly equivalent to the net solar radiation absorbed (~240 W/m 2 ). Step 2: Trace gases contribute to the natural greenhouse effect.

A friend asked me if a discussion paper published on Statistics Norway’s website, ‘ To what extent are temperature levels changing due to greenhouse gas emissions? ’, was purposely timed for the next climate summit ( COP28 ). I don’t know the answer to his question. But this discussion paper is problematic for sure.

Since it was a control simulation with no external “forcing” (no greenhouse gas changes, no variations in solar output, no volcanic eruptions, etc.), any oscillation that was produced has to be internally generated. Consider a parallel analysis (Figure 1-right) of the CMIP5 historical simulations.

We know we must now work to both cut greenhouse gas emissions to reduce the severity of climate change and at the same time work to adapt to the impacts we can no longer avoid. To be sure, there is much that Gleick and I agree upon. “We We know how to provide safe water and sanitation to the billions who still lack it,” he writes. “We
